Question

The perimeter of a rectangle is 320 meters its sides are in the ratio of 5:3than its area is

Answer 1

let the sides be 5x n 3x
so perimeter will be 2(5x+3x)
ATQ
2(5x+3x) = 320
2*8x = 320
x= 320/16= 20
so the sides r 5* 20= 100 n 3*20= 60

so area = 100*60 m2= 6000m2

hope it helps u

Answer 2

Let length be 5x and breadth be 3x

Perimeter = 320
2(l+b) = 320
2(5x+3x) = 320
2(8x) = 320
8x = 320/2
x = 160/8
x = 20

Length = 5(20) = 100 m
Breadth = 3(20) = 60 m

Area of the rectangle = length × breadth
= 100 × 60
= 6000 m²
